Many time-critical applications require predictable performance. Tasks corresponding to these applications have deadlines to be met despite the presence of faults. Failures can happen either due to processor faults or due to task errors. To tolerate both processor and task failures, the copies of every task have to be mutually excluded in space and also in time in the schedule. We assume that e...

The location of ground faults in railway electric lines in 2 × 5 kV railway power supply systems is a difficult task. In both 1 × 25 kV and transmission power systems it is common practice to use distance protection relays to clear ground faults and localize their positions. However, in the particular case of this 2 × 25 kV system, due to the widespread use of autotransformers, the relation bet...

This paper analyses two different approaches of fault distance location in a double circuit transmission lines, using artificial neural networks. The single and modular artificial neural networks were developed for determining the fault distance location under varying types of faults in both the circuits. The proposed method uses the voltages and currents signals available at only the local end...

We present a fast local clustering service, FLOC, that produces nonoverlapping and approximately equal-sized clusters. The clustering is such that all nodes within unit distance of a clusterhead belongs to its cluster, and no node m units away from the clusterhead may belong to its cluster. By asserting m ≥ 2 FLOC achieves locality: effects of cluster formation and faults/changes at any part of...

the most enigmatic problems with the nearly 200 salt domes pierced in the persian gulf and in the zagros mountain ranges (zmr) in southern iran, a unique morphology in the world, have been the matter of this study, which is based on a combination of field work, enhancement of satellite and aerial photographs etc. in the zmr, structural anomalies are frequently associated with similar facies dis...

The traditional approach to fault tolerant computing involves replicating computation units and applying a majority vote operation on individual result bits. This approach, however, has several limitations; the most severe is the resource requirement. This paper presents a new method for fault tolerant computing where for a given error rate, , the hamming distance between correct inputs and fau...

This paper presents the novel approach in protection and detection techniques of Alternator stator winding from the earth faults which are simulated between 2% to 10% distance point from the alternator neutral, since the impedence at that distance is very high we can not detect or protect by normal methods. The transient produced is analyzed in discreet Wavelet transforms. The potential of usin...
